摘要
A novel complex Cu（PPh3）2（acac） 1 （PPh3 = triphenylphosphine, acac = acetylacetone） was obtained by a solution reaction and structurally characterized by X-ray diffraction. The crystal belongs to monoclinic, space group P21/n with a = 13.7361（8）, b = 12.8204（7）, c = 19.7638（13）A, β = 95.946（2）^o, C41H37CuO2P2, Mr= 687.19, V = 3461.7（4）A3, Z = 4, Dc = 1.319 g/cm^3, S = 1.067,μ（MoKa） = 0.758 mm^-l, F（000） = 1432, R = 0.0403 and wR = 0.0990. Complex 1 is characterized by an isolated structure. X-ray structure analysis of I shows that acac behaves as a chelating ligand and PPh3 coordinates as a monodentate ligand to the Cu（I） atoms. Photoluminescent investigation reveals that the title complex displays a strong green-light emission.
